Effortless precision for woodworking Accurate, repeatable measurements: Brass adjustment screws let you quickly set and lock the scale; slide the ruler into the desired position for immediate, reliable marks. Precise parallel scribing: Knurled screws enable fine adjustments for parallel lines, improving layout speed and reducing rework. Durable, long-lasting construction: Aluminum-alloy body with a stainless finish resists wear and keeps the tool looking and performing well over time. Portable and convenient: Lightweight positioning blocks make the tool easy to store and carry to job sites or workshops. What this tool does for you Simplifies layout: Quickly mark exact dimensions and parallel reference lines without constantly recalibrating. Saves time: Fast, secure scale locking and smooth ruler positioning reduce the time spent on measurement setup. Improves accuracy: Fine control from knurled screws helps maintain parallelism and consistent spacing across multiple boards. Key attributes Function: Woodworking compass and scribe for accurate measurement and parallel line marking. Adjustment: Brass screws for scale setting and locking; knurled screws for precise parallel adjustment. Materials: Aluminum-alloy body with stainless finish for strength and corrosion resistance. Portability: Lightweight positioning blocks for easy storage and travel. Practical use scenarios Cabinet and furniture layout: Mark accurate, parallel reference lines for joinery, hinges, and hardware placement to ensure consistent alignment across parts. On-site carpentry and trim work: Carry the compact tool to a job site for fast, repeatable measurements and scribing on door frames, moldings, and panels. Workshop production runs: Set and lock the scale to reproduce the same scribe spacing across multiple workpieces without recalculating measurements. Why choose this tool Clear, repeatable settings and robust materials let you focus on your work instead of frequent measuring and correction. Designed for straightforward operation: adjust, lock, and scribe—no complex calibration required.
